Carbazolothiophene-2-carboxylic acid derivatives as endothelin receptor antagonists

The SmI2-promoted three-component coupling reaction of thiophene-2-carboxylate, indole-2-carbaldehyde and acetophenone provides an expedient route to a series of tetracyclic carbazolothiophene compounds bearing the indole and thiophene rings. A
